Czech the time Valentino, Lorenzo is faster!

After a short summer break, the riders are straight back on with the job in hand with Spaniard Lorenzo who has had three wins here previously, managing to complete the Brno 5.4km course in one minute 56.595 seconds, only narrowly ahead of Rossi but ahead all the same.

"It's a great thing to start the weekend in such a strong way and I've had a good sensation and feeling with my bike from the first moment today. This isn't usually the case so I'm really happy. I like this track a lot" said the Yamaha No. 2.

Chasing second placed Rossi's time was Honda's Daniel Pedrosa, who was a hair's breadth over half a second slower than the Italian leader, with Colin Edwards fourth fastest over the practice line with a time of 1:57.741.

Australia's Casey Stoner will miss the next three rounds of the MotoGP World Championship in an attempt to conquer his mystery illness.

The star's replacement Mika Kallio, has been relishing his opportunity to ride the Ducati, managing to put in a better time than some of the more veteran riders.

Kallio managed 1:58.302... not bad for an 800cc newbie!

The Rizla Suzuki bikes have released their new engine for this weekend.

Loris Capirossi and Chris Vermeulen believe that there is a lot of potential in the new engine they are using at Brno and they're eager to discover its full capability on the Czech circuit.

Only Capirossi however, managed to make it into the top ten on the new engine through Friday's practice.
